One of the most detailed sections, it regulates cement, aggregates, water, admixtures, concrete mix design, production, transport, placing, compaction, curing, formwork, reinforcement, joints and quality control. JKR permits the use of various cementitious materials (CEM I, GGBS, PFA, silica fume) and requires aggregates to comply with MS 30 and EN 12620. The standard also specifies minimum compressive strength for lightweight foam concrete (2.8 N/mm² for hollow blocks).
: Smoothness tolerances and crack prevention.
: This framework harmonizes local construction practices with Malaysian Standards (MS) and British Standards (BS), ensuring that Malaysian infrastructure meets global engineering criteria.
Specifies structural integrity testing (PDA testing), load testing criteria, and permissible alignment tolerances. Section D: Concrete Works standard specification for building works 2020 jkr pdf
Jabatan Kerja Raya Malaysia (Public Works Department). Release Date: January 2, 2020 (Ref: JKR 20800-0226-20).
The specification is vast, covering nearly every aspect of building construction, including:
It incorporates updated Malaysian and international standards, ensuring buildings are safe and durable. One of the most detailed sections, it regulates
Covers soil improvement techniques (e.g., geotextiles, geocells, geoweb, fibromat, coir logs) to enhance bearing capacity, reduce settlement and ensure long‑term slope stability.
: The 2020 specification places a stronger emphasis on sustainable materials, waste management, and industrialised building systems (IBS) to support Malaysia's green building initiatives. Core Sections and Technical Breakdown
The 2020 edition serves as a mandatory reference for contractors to ensure high technical performance, safety, and durability in building works. It integrates current technology and updated national (MS) and international standards to align with evolving government policies. Key Sections and Contents The specification is comprehensive, divided into 25 technical sections covering the lifecycle of a building project: Preliminaries (Section A): : Smoothness tolerances and crack prevention
Rules for site clearing, soil handling, and precise subgrade preparation.
